YOKOTA AIR BASE, Japan — International pressure continues to mount on Japan to address the problem of parental child abduction within its borders.During a meeting Friday with Japan’s Minister of Justice in Tokyo, officials from the European Union as well as representatives from Belgium, Colombia, Germany and Hungary joined the call for Japan to sign the 1981 Hague Convention on the Civil Aspects of International Child Abduction. The act essentially prevents parents from absconding with their children to or within the 82 signatory countries.
